"Throughout our career, we've been fortunate to only cancel a handful of shows and it's not something we take lightly. Unfortunately, today we have to announce that we will not be playing Self Help Festival on Saturday," they explain via Instagram.

"Matt's recovery from throat surgery is not healing as quickly as planned and, per his doctor, he can't perform. Everything went well, he just needs more time to heal so he can play many shows in the future. Thank you for understanding.”

Self-Help Festival will host sets from A Day To Remember, Papa Roach, Of Mice & Men, Knuckle Puck, State Champs and loads more.
